Hi, there--
.
You first need to find the measure of a congruent angle with a degree measure between 0 degrees and 360 degrees (an angle less than or equal to one rotation around the unit circle.) You find this by adding an integer multiple of 360 to -675 degrees to give a value in that range. In this case we add 2*360=720
.

.
An angle with a measure of -675 degrees is congruent to an angle with a measure of 45 degrees.
.
45 degrees is one of those benchmark values in trigonometry. You should recognize right away that

That's it. Feel free to email me via gmail if my explanation is unclear.
